    摘要： A toner for developing electrostatic latent image is disclosed. The toner comprise of particles having a volume average particle diameter of from 3 to 8 &mgr;m, and said resin is obtained by either emulsion polymerization, mini-emulsion polymerization employing or suspension polymerization employing thioglycerin or at least one compound selected from compounds represented by the Formula (1) as the chain transfer agent. HS—R1—COOR2  (1) In the formula, R1 is an aliphatic group having carbon atoms from 1 to 10, which may have a substituent, and R2 is an aliphatic group having carbon atoms from 1 to 15, which may have a substituent.

    摘要： A toner for developing an electrostatic image is disclosed. The toner is composed of association of a plurality of fine polymer particles, and the total volume of pores having a diameter of not more than 0.1 .mu.m on the toner surfaces is not more than 30 percent of the total toner volume. An image forming method employing the same is also disclosed. A toner which does not result in an unstable charge amount over an extended period of use can be obtained.
